The invention further discloses a wastewater defluorination method using the wastewater defluorination device, the wastewater defluorination device is simple in structure, the defluorination method is simple in process and good in defluorination effect, and the defluorination efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a waste water defluorination device and a waste water defluorination method. Background technique [0002] Chemical industry, electrolysis, and electronic component manufacturing industries will produce a large amount of industrial wastewater in the manufacturing process. These industrial wastewaters contain high fluorine content. If they are discharged without treatment or if the treatment is not up to standard, it will cause great harm to the environment. pollute. In real life, the concentration of fluoride ions in drinking water should generally be controlled at 0.4-0.6 mg / L. Drinking water with a fluoride ion concentration greater than 1 mg / L for a long time will be extremely harmful to the human body, and serious cases will cause dental fluorosis. , skeletal fluorosis and other diseases will eventually even cause people to lose their ability to work. At the ...

In real life, the concentration of fluoride ions in drinking water should generally be controlled at 0.4-0.6 mg / L. Drinking water with a fluoride ion concentration greater than 1 mg / L for a long time will be extremely harmful to the human body, and serious cases will cause dental fluorosis. , skeletal fluorosis and other diseases will eventually even cause people to lose their ability to work. At the same time, it will also cause various infectious diseases, cancer and newborn defects, etc., seriously affecting people's health

[0003] The cost of the existing defluoridation equipment is high, the defluorination process is relatively complicated, and multiple treatments are required to make the wastewater meet the discharge standard, and the treatment efficiency is low, which brings great inconvenience to the enterprise
